All qualified electricians,
I've been doing major moving around of equipment in my shop and was trying to decide what to do with a JET 1236P (mfr '79) engine lathe I acquired many years back. It came with a 110V plug attached, has a 2HP dual voltage (on the tag) motor that draws 28/14amps depending on how its wired.
I've always had problems with the motor. It will only start if the motor has a zero (no belt) load, and will only power the lathe at lower loads. Any serious load will pop the 30amp breaker. It has a 20' dedicated 10gauge line.
Although it appears from the [Taiwanese] tag it can be wired for dual voltage, it appears to have been modified (there simply aren't enough wires coming out of it) for one voltage. So to cut to the chase.
Yesterday I hooked it up to a 220 source and it ran great. I only ran it for about 45 seconds, but even under a brief very heavy load did not overheat. So....
Anybody's thoughts would be welcome. What happens when a 110 motor is run on 220? What should I be looking for? A pic of the motor is attached for your amusement.
